As we move to higher performance communications systems, more complex algorithms are required in channel coding architecture to keep innovating. We deliver standards compliant solutions such as Turbo, a highly parallel architecture used in 4G LTE. For 5G NR we provide LDPC complete chain for the data channels and Polar complete chain solutions for the control channels all to the required 3GPP compliant specification.

LDPC

By focussing on 5G NR, we have created an innovative LDPC solution that provides the best of block-parallel and row-parallel architectures, resulting in maximum performance and efficiency. This innovative design combined with configurability enables flexible LDPC decoders with high throughput, low latency, and high hardware efficiency without introducing error floors for high throughput communication systems.

  • Proven in IEEE standards, selected for data channel in 5G NR
  • Complete 3GPP compliant chain
  • 16x latency improvement (to support numerology 4)
  • Supports full code block and transport block processing
  • Open standard software API’s (DPDK) and reference kits
  • Delivered in multiple form factors for ASIC, FPGA and Software only
